Python | Numpy numpy.ndarray.__lt__() Last Updated : 29 Oct, 2022 Comments Improve Suggest changes Like Article Like Report With the help of numpy.ndarray.__lt__() method of Numpy, We can find that which element in an array is less than the value which is provided in the parameter. It will return you numpy array with boolean type having only values True and False. Syntax: ndarray.__lt__($self, value, /) Return: self<value Example #1 : In this example we can see that after applying numpy.__lt__(), we get the simple boolean array that can tell us which element in an array is less than that of provided parameter. Python3 # import the important module in python import numpy as np # make an array with numpy gfg = np.array([1, 2, 3, 4, 5, 6]) # applying numpy.__lt__() method print(gfg.__lt__(4)) Output:[True True True False False False] Example #2 : Python3 # import the important module in python import numpy as np # make an array with numpy gfg = np.array([[1, 2, 3, 4, 5, 6], [6, 5, 4, 3, 2, 1]]) # applying numpy.__lt__() method print(gfg.__lt__(4)) Output:[[True True True False False False] [False False False True True True]] Create Quiz Comment J jitender_1998 Follow 0 Improve J jitender_1998 Follow 0 Improve Article Tags : Python Python-numpy Python numpy-ndarray Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
